Fiber-Anchored Sealing Profile for Stable Embedded Gaskets
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Sealing profiles in molded parts, such as concrete or plastic tubings, often experience displacement during assembly due to inadequate anchoring, leading to deformation and failure to maintain a secure seal.
Innovation Solution
Incorporating a layer of non-woven, felt, or random fibers that are firmly connected to the sealing profile, either instead of or in addition to anchoring feet, to enhance adhesion to the molded part, thereby preventing displacement and improving the seal's resistance to forces.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If anchoring feet are used to secure the sealing profile in the molded part, then the seal should remain fixed in position, but the continuous anchoring feet cannot fully withstand forces acting in the longitudinal direction, leading to displacement and compression of the gasket
Solution Approach 1:
The patent combines anchoring feet with a fiber flocking layer made of textile fibers to create a composite anchoring system. The fiber flocking provides additional friction and mechanical interlocking with the curable material, complementing the anchoring feet to resist longitudinal forces that would otherwise cause gasket displacement and compression.
Solution Approach 2:
The fiber flocking layer creates a porous structure that allows curable material to penetrate and bond with the fibers, creating a mechanically interlocked anchoring system. This porous fiber network increases the surface area for bonding and provides multiple anchoring points throughout the gasket profile.
2Stability of the object's composition
If the sealing profile is embedded in the molded part using conventional anchoring methods, then the seal should be held in place, but displacement still occurs during assembly leading to deformation of the seal
Solution Approach 1:
The combination of anchoring feet with the fiber flocking layer creates a more robust composite anchoring system that better resists assembly forces. The fiber network distributes stresses more evenly across the gasket profile, preventing localized deformation while maintaining positional stability during assembly operations.
3Reliability
If a fiber flocking layer is added to the sealing profile to improve anchoring, then the adhesion to the molded part is enhanced, but the device complexity increases
Solution Approach 1:
The fiber flocking layer is applied as a relatively simple porous coating on the gasket profile. This porous structure provides extensive surface area for bonding with the curable material while adding minimal structural complexity. The fibers can be embedded directly into the molding process, integrating the anchoring function without requiring separate assembly steps.

AI summary
The invention relates to a sealing profile for embedding into a moulding of curable material, in particular a concrete or plastic moulding, and to a sealing arrangement comprising such a sealing profile. The object of the present invention is to provide a sealing profile for embedding into a moulding of curable material that can be anchored into the moulding in particular such that displacements of the seal in its seat occur to a significantly lesser extent, if at all, when installing or assembling the mouldings. The object is achieved by a sealing profile (1) with a profile region (2) having a profile region surface (4) which is directed towards the moulding (3) after embedding the sealing profile (1), wherein the profile region (2) has, at least in one subregion (6), a non-woven, felted or random fibre layer (5) which is fixedly connected to the sealing profile (1) and which extend beyond the profile region surface (4).
